Backflow happens when water flows in the wrong direction within your plumbing system, allowing contaminated water to enter your clean water supply. This can occur due to sudden changes in water pressure, and it poses a serious risk to your health. Backflow can carry pesticides, bacteria, and other pollutants straight into your home’s drinking water.
To prevent this, Louisiana law—and specifically the Sewerage & Water Board of New Orleans (SWBNO)—requires property owners to install and maintain approved backflow prevention devices. But owning a device isn’t enough. State rules now mandate that these devices be tested annually by a qualified professional.
What the Law Says in Louisiana
In Louisiana, and especially in New Orleans, annual backflow testing is no longer just a best practice—it’s the law. As of December 1, 2024, all commercial and certain residential properties must:
- Have a certified backflow prevention device installed.
- Complete annual inspections performed by a licensed and endorsed professional.
- Submit passing test results to the water authority within the required deadline.
- Repair or replace any failed devices immediately and retest before returning them to service.
Only a licensed plumber in New Orleans with a Water Supply Protection Specialist (WSPS) endorsement, like Blair Plumbing, can legally install, repair, and test these devices in compliance with state and local regulations.
Backflow Prevention Is About More Than Compliance—It’s About Safety
Backflow prevention isn’t just about passing an inspection—it’s about protecting the health of your family, your neighbors, and the entire community. When water flows backward into the public water supply, it can carry fertilizers, pesticides, chemicals, or harmful bacteria from private properties into the drinking water system. Even a minor lapse in device maintenance can lead to serious contamination risks.
That’s why Louisiana now enforces strict testing requirements and why it’s critical to work with a licensed plumber in New Orleans who also holds a Water Supply Protection Specialist (WSPS) endorsement. With Blair Plumbing, you get a team that not only understands the letter of the law but also prioritizes the safety and long-term reliability of your water system.
